Formats for Reading Books

There are so many formats that you can use these days to read a book from audio to actual paper books (the traditional way) to actually downloads on your computer. Audio books have revolutionised driving in traffic and listening as you wait on the highway is a real benefit. You might like to see your plays performed live on stage rather than reading them. I have used each of the formats in this short list of 10. I am sure there are actually more options than these. I Just have not thought of them or come across them.
